Nanocomposites with exfoliated 2D materials are highly sought after due to resulting material enhancement of barrier and increased modulus among others. In the past, this was achieved by using polyols that were effective but caused a significant drop in the glass transition temperature of the nanocomposite. In this contribution, α-zirconium phosphate (ZrP) nanoplatelets were covalently modified to allow for dispersion in solvents with varying hydrophobicity and poly(methyl methacrylate) (PMMA) for the first time. The nanoplatelets were prepared by using a polyetheramine surfactant to achieve exfoliation, followed by modification with epoxides. Combinations of different epoxides were shown capable of tuning the functionality and hydrophobicity of the exfoliated ZrP in organic media. After grafting glycidyl methacrylate and cyclohexene oxide to the surface of ZrP, an free radical polymerization of MMA allowed for high concentrations of self-assembled exfoliated ZrP in a PMMA matrix.

Background: As compared to withholding parenteral nutrition (PN) until one week after intensive care unit (ICU) admission, Early PN prolonged ICU dependency in the EPaNIC randomized controlled trial (RCT). The Refeeding RCT showed improved outcome by temporary macronutrient restriction in ICU patients developing refeeding hypophosphatemia, defined as a phosphate decrease of > 0.16 mmol/L to levels < 0.

The rapid development of therapies for severe and rare genetic conditions underlines the need to incorporate first-tier genetic testing into newborn screening (NBS) programs. A workflow was developed to screen newborns for 165 treatable pediatric disorders by deep sequencing of regions of interest in 405 genes. The prospective observational BabyDetect pilot project was launched in September 2022 in a maternity ward of a public hospital in the Liege area, Belgium.

Vitamin D deficiency is common in patients with chronic kidney disease (CKD) and associates with poor outcomes. Current clinical practice guidelines recommend supplementation with nutritional vitamin D as for the general population. However, recent large-scale, clinical trials in the general population failed to demonstrate a benefit of vitamin D supplementation on skeletal or non-skeletal outcomes, fueling a debate on the rationale for screening for and correcting vitamin D deficiency, both in non-CKD and CKD populations.

The synthesis of highly efficient and environmentally friendly flame retardants through the synergistic interaction of boron, phosphorus and nitrogen is becoming a new research direction. In this study, N-DBSPA, a flame retardant with high flame retardancy, high thermal stability and high efficiency, was prepared by the reaction between pentaerythritol borate and amino trimethylene phosphate, and the limiting oxygen index (LOI) of the modified cotton fabric increased from 18 % to 44.7 % at a weight gain (WG) of 20.
